The invention provides an electrical secondary equipment state evaluation method and a system thereof. The method comprises the following steps: presetting a weight proportion of each maintenance state parameter of secondary equipment to a maintenance state value of the secondary equipment, and establishing a calculation model of the secondary equipment maintenance state value; acquiring real-time detection values of each maintenance state parameter of the secondary equipment, calculating the maintenance state value of the secondary equipment according to the calculation model of the secondary equipment maintenance state value; determining a maintenance state of the secondary equipment according to a calculation result of the maintenance state value of the secondary equipment. According to the method and the system provided in the invention, the maintenance state of the electrical secondary equipment of an electrical system can be determined comprehensively in order to maintain the electrical secondary equipment timely and prevent various fault problems brought by lack of electrical secondary equipment maintenance.
Description
technical field [0001] The invention relates to the technical field of electric power secondary equipment maintenance, in particular to a method for evaluating the state of electric secondary equipment and a system for evaluating the state of electric secondary equipment. Background technique [0002] With the development of the electric power industry, the electrical equipment maintenance system is changing from the planned maintenance mode to the condition-based maintenance mode. The core task of condition-based maintenance mode is to evaluate the operation and maintenance status of equipment, so as to arrange maintenance time and maintenance items reasonably, and prevent accidents caused by insufficient maintenance. [0003] The routine operation and maintenance state evaluation process of power secondary equipment mainly includes the selection of equipment characteristic state parameters, and the integration of state parameter information to obtain the equipment health s...
